4 Claims.

This invention relates to an improved means for securing wooden strips, such as sleepers, furring strips, or the like, to concrete walls or floors.

An object of this invention is to provide an improved anchor which is adapted to be partly embedded in concrete and partly projecting therefrom, the projecting portion of the device \being formed with tangs for holding wooden strips firmly with respect to the concrete.

Another object of thi invention is to provide an attaching means of this .kind which is of simple construction, so that it can be cheaply and quickly made and will provide the necessary firm gri or holding means for the wooden strips.

A further object of this invention is to provide a device of this kind embodying a fixed washer or plate, which provides a limiting means for limiting the extension of the anchoring portion thereof in the concrete,

To the foregoing objects and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawing, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing: I

Figure 1 is a fragmentary sectional view of a concrete floor, having a strip anchoring means embedded therein, which is constructed according to an embodiment of this invention.

Figure 2 is a plan view of the device shown in Figure 1.

Figure 3 is a detail side elevation of a modified form of this invention.

Referring to the drawing, the numeral Ill designates generally a concrete floor, or other structure such as a wall, or the like, and the numeral l l designates a wooden strip which is adapted to be secured to the outer surface I3 of the concrete H).

In order to provide a means whereby the strip II will be firmly anchored with respect to the concrete I0, I have provided a strip anchoring means, including an elongated bar [2, which is provided at its inner end with a head or washer 14. The bar l2 also has fixed thereto a circular washer or plate [5, which is disposed between the ends Of the bar I2 and provide a stop, which is adapted to limit the extension of the anchoring portion l6 of the bar [2 into the concrete [0.

The bar l2 includes a projecting pointed member II, which extends outwardly or upwardly from the stop plate l5, and the point I! is provided with a plurality of outwardly projecting tangs H3. The point I! is adapted to be driven into the strip H from the inner side thereof and is of such length that the point I! will be substantially entirely embedded in the strip II, the latter being substantially thicker than the length of the point l'l, so that no portion of the point l'i will project through the strip I I.

Referring now to Figure 3, there is disclosed a modified form of this invention, which includes an anchoring bar I9, which is longitudinally bent of substantially corrugated configuration, and is formed with an inner anchoring member 20.

A plate 2| is fixed to the outer end of the anchoring member [9 and is adapted to engage the outer surface of the concrete, so as to limit the extension of the anchoring member I9 within the concrete. A point 22 is formed integral with the anchoring member l9 and is provided with a plurality of laterally projecting tangs 23, which are struck from the outer surface thereof and are inwardly bent so that when the point 22 is driven into the wooden strip, the tangs 23 will hold the point firmly in the strip.

In the use of this device the anchoring construction has the anchoring member thereof embedded in the concrete l0, and when the concrete has set, the strip ll may be engaged with the point H and the strip ll struck with a tool, so as to force the strip H downwardly and the point I! into the strip. These strips can be held in alignment in any suitable manner, and after the stri II has been forced over the point H the inwardly projecting tangs [8 will hold the strip ll firmly on the point II.

The exact configuration illustrated is regarded as the optimum, but some of the desirable results inherent in this disclosure may be obtained by various slight modifications including. some end of said member, and inwardly directed barbs carried by said point,

2. An anchor as set forth in claim 1 including a plate fixed to the inner end of said member.

3. An anchor as set forth in claim 1 wherein said memebr is of substantially corrugated shape.

4. An anchor as set forth in claim 1 wherein said member is of substantially serpentine shape and the inner end thereof is extended at substantially right angles to the length thereof.
